FRIEDRICH( WEGMANN, on Nantais-ITALY] To all whom it may concern Be itknown that I, FRIEDRICH WEGMANN, of Naples, Italy, have invented certainnew and useful Improvements in Condenser-s or Condensing Appara- \tusfor Steam-Engines, &c.; a'nd I do hereby declare the following to be afull, clear, and exact description of' the sam 1 My invention relates toa new arrangement of coudensing apparatus fully described hereafter,adapted to economize a great portion ot' the water necessarytbr-t-he'operation of' ordinary condenser-s, and which may furnishdistilled water when desired.

The improved condenser may he adapted to' engines either alone or inconnection with any of the ordinary condensers in use for engines ot'either high orlow pressure.

In order ,to enable others familiar with apparatus of this class to makeand use my invention, I will now proceed to describe its constructionand operation, ret'-A erence being had to the accompanying drawing whichforms a part of this specilication, and in which- Figure 1 is a view ofthe condensing apparatus, partly in section, and Y Figure 2,a sectionalplan of one of the condensing vessels.

Similar letters refer to similar parts throughout the several views.

The apparatus consists- First, of a receptacle, A, somewhat analogous tothe surface condensers in common fuse, and which leceives directly theexhaust steam of the engine;

Secondly, of a upright cylindrical watervessel, B, which serves as awasher for the non-condensed steam -leaving the first receptacle A; and

Thirdly, of a series of receptacles, C D E, precisely similar to the"first receptacle A, (see fig'. 2,) and in which the steam continues tocirculate until completely condensed.

, The. escape steam first enters the receptacle A through the pipe a,and circulates in the interior of the tuheslb, and in the. spces c,which communicate with these tubes, as shown by the arrows in Iig. 2.

The steam is then taken through the pipes l into a 4tubular compartment,t, at the top of the vessel B,

this compartment being open at the bot-tom, so that the water which ismaintained at the level ein the, outer vessel may also rise to the sameheight in the said compartment. This forces the steam, in ordet` topenetrate into the vessel B, to traverse a layer of water which deprivesit of allimpnrities.

The water in the vessel B is kept at abouta temperatureof 8 00, sothat,by the vacuum, a constant `evaporation is produced at its surface, andthe steam thus .generated passes through the pipe f, and trav erses,consecutively, the three refrigerating vessels, C, D, and E. It leavesin a liquid state through the pipe y, where it can be collected asdistilled water, or

it maybe drawn by the feedpump of the engine and passed into the` vesselC through the pipe'lt to serve as cooling water. 1

The water, after passing around 'the tubesl in the vessel C, leaves hythe pipel t', which conducts it into the first receptacle A, whereit-againservcs as cooling water, and finally passes ot through the pipej, to be used as feed-water for the boiler.

The pipe K, provided with a cock,k, communicates with a well o rreservoir of cold water, and this water is drawn through the vessel E,around the pipes b,

and through the pipe i by the air-pumpof the ordinary condenser, if theapparatus is provided with acondenser, or by a special air-pump in thecontrary case, and this pump throws-the same water through the vessel Dby the pipes an. The water leaves this latter vessel through the pipe u,and part of it, flows into the vessel 13, to compensate for thewasteresulting from evaporation, and the other portion is rejected.

Where a sutliciently large quantity of water is not attainable,a current.of cold air can be passed into the vessel E with the same result.

r1 he pipe O, furnished with acock, r, communicates at one end with theair-pump, or with the pipe t', leading to the same, and at the oppositeend with the interior of the tubes b. The object of this pipe is torapidly cause a vacuum in the tubes b 'and spaces c,

when operating.

When the apparatus is in operation, the cock r' should be partiallyclosed, a small passage only being -required to carry oil` the air whichalways remains after the condensation of the steam.

The entry of' the wat-er into the vessel B is regulated by the cock p onthe pipe n, and the cock s .has also in it interior guides c, to hinderoscillation on the surface ot the water, and to thus facilitateevaporation.

WVith this apparatus the following advantages are obtained:

The boiler is fed with distilled water, and'consequently incrustations'are avoided, and the use of this feed-water vat a high temperature, witha sulicient vacuum behind the piston, effects considerable economy .offuel.'
